CAD Surface Patch Strategies

 well..more specific to Solidworks but the general thoughts are applicable to many software packages.

In many instances you can fillet and trim surfaces together. Sometimes you want a more gradual transition to the edge and lofts and surface fills are more handy

You might be tempted to capture too much detail in one surface feature as on the right. Try to have your surface patched together with simply curved surfaces that only have one inflection per patch.

That might look messy but it is much easier to control, and should create an overall lighter model

 Sweep surfaces that have a consistent section or shape.
